A full roof replacement means stripping the old roofing material down to the deck (or at least the top layer or two, where code allows), inspecting and repairing any rotted or damaged decking, installing new underlayment and flashing, and laying down new shingles, tile, metal, or membrane. Installation work covers the same process on new construction or additions. It's a bigger job than a repair: expect a crew on your property for one to three days, dumpsters or trailers for tear-off debris, and permits pulled with the city before work starts.
Stamford's mix of older colonials, shoreline homes exposed to salt air and wind, and newer builds means contractors here deal with a wide range of roof types and pitches. We're tracking 38 roof replacement and installation businesses serving the area, from small crews to larger regional outfits.
What to look for before you hire
Ask for proof of Connecticut contractor registration and liability insurance, and confirm the crew is covered for workers' comp, not just the company office. Get a written estimate that specifies materials (shingle brand and line, underlayment type, flashing metal), not just a total price. Check whether the quote includes decking repair as a line item or an allowance, since surprises here are common once tear-off starts. A manufacturer certification (GAF, CertainTeed, Owens Corning, etc.) usually unlocks stronger warranty coverage than a standard installation.
